Fresh install of Xubuntu 16.04.2. Everything seems correct, but all the Libreoffice menus are in the wrong language. I've checked - locale is correctly set (en_GB.UTF8), and other GUI applications are coming up correctly in English.
I found that some of the support files I'd normally expect for UK use were not installed (hunspell-en, the UK hyphenation support, the normal en_GB language support. Adding them in makes no difference at all - menus are still in the wrong language (no idea what it is - could be Arabic, characters are not the normal alphabet I would expect...).
As another attempt at a fix, I copied the ~/.config/libreoffice files from another Xubuntu 16.04 install (in which Libreoffice is using the selected English menus). Still no change.
Has anyone else seen this sort of problem, and (hopefully!) have suggestions as to how to fix it? I've done some searching but so far I've not found anything that matches this rather peculiar fault.
Any help gratefully accepted...
I've added a screenshot showing the language selection menu. If someone can identify the language and tell me how to select English, it would be a bit help. Seems odd that the heading is in English, but the rest isn't.
